PRINTING-PRESS.

To all whom it may concern:

Be it known that I, AUGUSTUS W. VAUGHN,

a citizen of'the United States, residing at Adel, in the county ofDallas and State of Iowa, have invented certain new and usefulImprovements in a Printing-Press, of which the following is aspecification.

The Objects of my invention are to provide a printing press of simpleand durable in position relative to the type asthis printing rollerpasses over said type. i

A further ob ect.1s to provide a mechanism which will automaticallyraise the frame over which the printing roller passes when said rollerreaches its extreme ou tcr limit of movement and maintain said frame ina raised position While the roller is moved to its point of starting andthus prevent the paper from "being inked on the rear movement of theroller, and further to provide a mechanism for automatically releasingthe frame from raised position and allowing it to move to its ing rollerwhie tical movement. h 1 My nvention consists in certain details 1n itslowered position as the .roller approaches its point of starting.

A- further ob'ect is to provide a ball bearli is designed to be placedon the ends of the shaft upon which the print ing roller is mounted andis designed to engage the lower portions of the frames for maintainingsaid printing roller, against verthe construction, arrangement andcombinationof the various parts of the device,.

whereby the objects contemplated are attained as hereinafter more fullyset forth,

pointed out in my claims and illustrated in the accompanying drawings,in whichv Figure l shows'a side elevation of the complete printingpress.

The dotted lines in this view show the difierent positions of themechanism'for raising and lowering the frame upon which the printingroller is mounted and the printing roller at its outer limit of-.movement in dotted lines. Fig. 2 is a cross sectionalview of the ballbearing roller which Specification of Letters Patent.

is mounted on each end of the shaft upon which the printing roller ismounted. This View shows said shaft in cross section also. Fig. 3 shows,in perspective, one end of the printing roller with the ball bearingroller mounted upon the shaft which bears it. Fig. 4 is a detail view ofone end of'thcframe of theprinting press and of one side thereof and isa cross section cut through the line 4--4 of Fig. 5. Fig. 5 is a planview of the complete printing press. Fig. 6 is a cross sectional view ofthe printing roller and shows in cross section the mechanism foradjusting the paper in position on said roller. This view also shows aportion of one of the frames for holding the printing roller againstvertical movement.

Referring to the accompanying drawings, I have used the referencenumeral 10 to indicate the frame of the printing press which comprisesfour legs and connecting pieces between these legs. Mounted on the frame10 and extending longitudinally of it are the tracks 11 and 12, each ofsaid tracks having a rack 1.3 mounted thereon and extendinglongitudinally of them. .T he tracks ll and 12 are pivotally mounted at14- near the feed ing end of the printing press and are thus mounted toallow the outer end of said tracks to be raised and lowered. Theracks-13 are mounted on the outside of the top portion of the tracks 11and- 12 so as to form a flat sur face inside of the racks u on whichrollers hereinafter described are a owed to move as the. printing rolleris moved outwardly and inwardl on the racks 1'3. Mounted between t esetracks 11 and)? and near the central portion ofthenron the frame 10 isthe form bed'15 designed to. hold in position. the

forms of type and plate which are to be printed. Firmly attached to theoutside portion of each of the tracks 11 and 12 respectively are theframes 16 and 17, said frames being designed to maintain the printingroller ag'ainstvertioal "movement as it moves longitudinally of therinting frame.

Mounted on each'of-the rac rs 13 is a pinion wheel 18 designed to movelongitudinally of said racks. i wheels and firmly attached .to them isthe shaft 19 upon which the im ression roll 20 is mounted. This printingr0 ler is of the ordilounted between said pinion nary constructionhaving an opening 21 in its periphery and having the gri pers 22rotatahly mounted in one side of t ie opening, said grippers beingdesigned to be swung by a gearing to aposition for maintaining the paperfirmly relative to the impression roll as shown in Fig. 6 ol' thedrawings. A further description of this is not deemed to he necessary asthis form of impression roll is common in various printing presses.Rotatahlv mounted on each end of the shaft 19 and adjacent to thepinions 18 are the arms 23, said arms extending inwardly from theimpression roll and having the shaft 24 mounted between their innerends. Mounted between these arms 23 and on the shaft 21 are the flangedwheels 25 and 26 designed to move longitudinally over the inner portions27 and 28 respectivelv of the tracks 11 and 12 the pinions .18 novelongitudinally of the racks 13.

Extending diagonally across the frame and rotatably mounted lietween thearms 33 and in the supports 36 and 37 which. are attached to said arm isthe s ireading roller 36, so constructed that it will not only rotateover the forms which are placed upon the form bed 15 as the impressionroll is moved outwardly and inwardly, hutit will also move from the leftto the right a slight. distance and from the right to the left so thatthe ink will he evenly distributed over the forms.

Mounted on each end of the shaft 19 and outside of the pinions lb is aball or roller bearing .wheel 39 whose outer periphenv is designed toengage the under portion of the frames 16 and 17 as the shaft is movedlongitudinally of said frames, the inner portions of the rollers 39which are adjacent to the shaft 19 are cut away to receive the rollersor balls 40 which act on the interior of said rollers 39, and on theexterior of the shaft 19 as the shaft 19 is moved outwardly and inwardlyabove the frame It). It will be seen that as the shaft is rotated in onedirection above the frame 10, the rollers 3.) will he rotated in theopposite direction as they pass over said frame 10 as they engage theframe 16 and 17, thus rotating the rollers 39 in the same direction asthe shaft 19 is rotated.

Mounted on the extreme right end of the shaft 19 is an arm 41 the shaft19 being rotatable in said arm. Pivotally attached to the inner end ofsaid arm is a second arm 42 which is pivoted at its lower end to theframe 10. ltotatably mounted on the frame 10 and near its inner end isthe gear wheel 43. Pivotally attached to the gear wheel 43 and adjacentto the lower end of the arm 42 is an arm 44 designed to swing the arm 42on the pivot 45, and as the gear wheel 43 is turned. Rotatal ly mountedon the frame 10 and in mesh with the gear wheel 43 is the gear wheel 46which is capable of being driven by means of the crank 17 or from a owerwheel. As the gear wheel 46 is turner in one direction, the upper end ofthe arm 42 will be moved to its outer limit of movement and willcorrespondingly move the impression roll to its outer limit of movement,and as the gear wheel 46 is rotated in the opposite direction, the upperend of the arm, 42 will be moved inwardly and the printing roller willhe also moved inwardly. 'lhroughout the entire specification 1 mean bythe inner end of the machine that end where the papers to be printed areplaced upon the machine.

Extending across the outer end of the frame and through the slots 48 inthe tracks 13 is the rod 49 having the arms 50 firmly mounted at eachend thereof. At the lower end of each of these arms 50 is a curved slot51 designed to receive the pins 52 which are on the frame 10. As theupper ends of the arms 50 are at their inner limit of movement, the pins52 will be at the inner ends of the slots 51 and the tracks 13 willbe attheir lower limit of movement. \Vhen the upper ends of the arms 50 aremoved to their outer limit of movement, the pins 53 will be at the outerends of the slot 51 owing to the fact that swinging the upper ends ofthe arms 56 auses the lower portion in which the slots 51 are, to hemoved inwardly, and as the slots 51 are curved upwardly from their innerends to their outer ends, the tracks 13 will he in a raised positionwhen the pins 52 are at the outer ends of the slots 51.

livotally attached to the upper end of one of the arms 50 is a rod 53which extends longitudinall of the frame 16 and outside of it to thepivotally mounted lug 54 to which it is pivotally mounted. This lug,5elhas its pivotal point 55 at its upper end and the arm 53 is pivotallyattached to it at 56. The lower end of the lug '54- extends below theportion of the frame 1.6 upon which the roller 39 rolls and is designedto be engaged by the shaft 19 as said shaft passes by it.

When the impression roll is moved to its outer limit of movement, theshaft 19 engages the upper end of the arm 50 and causes it to be swungto its outer limit of movement and causes the outer end of the tracks 11and 12 to be swung upwardly and the tracks will he maintained in theirposition until the impression roll is drawn to its inner limit ofmovement, and the shaft 19 engages the lower end of the lug 54 whichcauses the upper end of the pivotally mounted arm 50 to be drawninwardly and thgs lower the outer ends of the tracks 11 and 1.2.

Mounted above the upper inner portion of the frame 11 and at the rear ofthe frames 16 and 17 is a feeding table 57 inclined from its "signed toallow -the printing roller 30 to be passed under it and toallow thepapers to be printed to pass over the feeding table- 51 and the guidingplate 58 into the grippers 22 which are mounted on the impression roll20. Attached to the inner upper portion of the frames 16 and 17 andbetween said frames is the rod 59 having a-series of guides 60 attachedthereto, and extending outwardly and downwardly therefrom so that theirlower ends engage the outer edge of the plate 58. These guides 60 areweighted so as to engage the plate 58 and constantly keep the paperbeing fed into the impression roll 1n a un form position so that'thegrippers 22 on the rinting roller will grasp the paper and t us it willbe wound around said roller. As the rod 59 is rotatably mounted, it willbe seen that the lower end of the guides 60 will swing upwardly anddownwardly and thus allow the paper to be passed between said guides andthe plate 58.

In practical use, the operator laces the paper to be printed on top ofthe ceding tale 57 and operates the mechanism of the device by means ofthe crank.47,which opera tion causes the impression roll to be movedfrom its inner limit of movement after the pa er has been engaged by theimpression rol 20 and the grippers 22 over the forms of type which aremounted on the form bed 15 to the outer end of the frame 10. As itappreaches the outer end of said frame, the

shaft upon which the impression roll is mounted engages the upper end ofthe arm which causes the said upper portion to be moved outwardly,'which causes the" outer end of the tracks Hand 12 to be swung upwardly.Then by reversing the rotary movement of the crank 47, the impressionroll moves inwardl until the shaft 19, upon which the printingroller ismounted, engages the lug 54, which causes the upper end of the arm50 tobe drawn inwardly, the outer ends of the tracks 11 and 12 t0 move totheir normal limit of movement, and the device is then in position forprinting the next sheet. The ink cylinder 31 is constantly rotated onaccount of its engagement with the rollers 29 and 30 and a constantfeeding of ink from the cylinder to these rollers is provided for}Having thus described my invention, what I claim and desire to secure byLetters Patent of the United States, therefor is 1.
